This article discusses the impact climate change will have on where people live. Climate change will drive human migration more than other events, a new report warns. But the worst impacts can be avoided.
Most of this population shift will take place in Sub-Saharan Africa, South Asia, and Latin America—three “hot spots” that represent 55 percent of the developing world’s populations.
This worst-case scenario is part of a ground-breaking study focused on the impacts of slow-onset climate, as opposed to more visibly dramatic events such as extreme storms and flooding. The report, Groundswell—Preparing for Internal Climate Migration, also shifts the focus from cross-border migration, which has drawn global attention as refugees and migrants flee war, poverty and oppression, to in-country migration, which involves many more millions of people on the move in search of viable places to live. The 143 million represent 2.8 percent of the three regions’ population.
